Its funny how wrong information can be repeated. I saw the first Australian article that made the claim of 510KW - 684 hp, and I dismissed it. No way the car is going to be sold as nearly 700 hp. However, it seems to have gotten picked up a few places for people to argue about.

The new Nissan GT-R doesn't land in Australia until early 2009, but the Japanese car maker is already working on a lighter and more powerful version If the new Nissan GT-R’s 353kW isn’t enough for you, wait until the debut of the GT-R V-spec, which promises 510kW of power courtesy of an increase in boost for the twin-turbo V6 engine.

Caught here at the Nurburgring test track in Germany, the GT-R V-spec has been set a target lap goal of under seven minutes and 25 seconds for the tricky, demanding circuit. That's 18 seconds faster than the cooking GT-R that is already quicker than a Porsche 911 Turbo.

The GT-R V-spec is also rumoured to have shaved 150 kilos off its (admittedly hefty) 1740kg kerb weight by the use of carbonfibre body panels and lighter, more effective carbon-ceramic brakes.

Those stoppers are fed cool air via a revised front splitter that boasts several new air intakes.
